There's also the alternative of not punishing it at all, because they're just using a first-come-first-serve public resource when they have no better alternative. I don't need to sleep on a park bench because I own a house with beds, so punishing me equally for it isn't really equality. Ironically I bet I actually could take a nap on a park bench with less chance of the cops being called than a homeless person anyway.
